• Format — 3,300+ free practice MCQs across 12 top-level topics, with instant explanations after every wrong answer.
• Duration — about 32 hours of focused practice; most learners spread it over 4–6 weeks.
• Level — beginner to advanced. Start from scratch with reasoning fundamentals, finish placement-ready with critical reasoning and input-output.
• Cost — completely free, including the verifiable completion certificate.
• Audience — engineering and management aspirants preparing for campus placements, aptitude rounds, CAT/XAT/GMAT, banking and SSC exams.
• Companion course — pair this with Quantitative Aptitude for full placement-test coverage.

The course is built for four audiences. First, engineering students 3–6 months out from campus placements who need to clear aptitude rounds at TCS, Infosys, Wipro, Cognizant, Capgemini, and similar mass recruiters. Second, MBA aspirants studying for CAT, XAT, NMAT, SNAP, and CMAT, where the LRDI section can be the difference between a 95th-percentile call and an interview shortlist. Third, candidates preparing for banking exams (IBPS PO, SBI PO, RBI Grade B), SSC CGL, and similar competitive exams where reasoning is a fixed scoring section. Fourth, working professionals revisiting reasoning for master's-program admissions tests like GMAT and GRE. If you fall outside these groups but want sharper pattern recognition and structured problem-solving, the foundations and depth layers still hold their value.

The curriculum is organised into three layers that map directly to the 12 topics. You can take them in order or jump to whichever layer matches your current level.

Foundations

The first three topics build the basics — what reasoning is, how patterns work, and the most common test patterns.

• Introduction to Logical Reasoning — reasoning fundamentals and the building blocks of pattern recognition. Sets the mental frame for the rest of the course.
• Series & Analogies — number series, letter and alphanumeric series, and verbal/numerical analogies. The most common opening section on aptitude tests; high-frequency and fast to solve once you know the pattern families.
• Coding & Decoding — letter coding, number coding, and symbol/operation coding. Three subtopics covering every coding style you'll see in placement tests.

Depth

The middle six topics are where most placement-test questions live — the meat of the course.

• Blood Relations — direct relations, coded blood-relation puzzles, and complex family-tree problems. A single diagramming convention applied across all three subtopics.
• Directions & Distances — direction concepts, distance calculations, and shadow/facing problems. Learn to track a person's path on paper without losing orientation.
• Syllogisms & Statements — syllogism basics, drawing conclusions from statements, and recognising statement types. Venn diagrams done minimally and quickly.
• Ordering & Ranking — linear ranking, comparative ordering, and multi-attribute ranking. Build the table, fill from constraints, commit late.
• Seating Arrangements — linear arrangements, circular arrangements, and constrained-seating problems. The single highest-density topic in CAT-style LRDI and banking PO mains.
• Puzzles & Scheduling — floor and position puzzles, scheduling problems, and grouping/matching puzzles. The big-grid problems that look intimidating but follow a fixed solving rhythm.

Placement edge

The final three topics close the gap between "I can solve" and "I solve under exam pressure".

• Input-Output — input-output basics, step-based transformations, and complex input-output patterns. A favourite of bank PO mains; rewards recognising the stage type fast.
• Critical Reasoning — arguments and assumptions, strengthen/weaken-the-argument problems, and inference vs conclusion. The GMAT/CAT-style reasoning that doesn't fit into a pattern-recognition box.
• Logical Reasoning in Practice — concept comparisons, pattern selection, and applied scenarios. The wrap-up topic that mixes everything and forces you to pick the right approach without being told the topic.

The two sections look similar on a placement test but test very different muscles. Quantitative aptitude is about numerical fluency — arithmetic, percentages, ratios, algebra, geometry, probability. You need formulas, calculation speed, and shortcuts. Logical reasoning is about structure — given a set of constraints, what must be true? You need diagramming habits, pattern recognition, and the discipline to write constraints down before committing to an answer.

Most placement tests blend both, and most candidates are stronger at one than the other. For CS and engineering students, quant usually comes more naturally out of the box — logical reasoning is the leverage section because there's more room to improve in less time. If you're stronger at reasoning already, pair this course with Quantitative Aptitude to close the other side. Both are free.

Active recall, not passive reading. Logical reasoning isn't a body of facts to memorise — it's a set of solving habits that only build under pressure. The best preparation is volume: solve hundreds of problems, see your wrong answers explained immediately, and let the patterns settle in. Textbooks and YouTube playlists work as starting context, but they can't replace the minute-by-minute friction of getting questions wrong and reading why.

That's the principle this course is built on. Every wrong answer triggers an explanation that names the pattern family, the trap, and the faster path. You don't need to take notes — repeated exposure to the same patterns across hundreds of MCQs does the encoding for you.

You see one question at a time. You answer. If you're right, you move on. If you're wrong, you get a written explanation — what the right answer is, what the pattern was, what trap you fell into. There's no theory dump, no video to watch, no slides to scroll. Just question → answer → explanation → next question, for as long as you want to practice. The platform tracks your accuracy per topic so you know where the gaps are. An AI guide is available alongside if you want a question explained differently or want to ask a follow-up.

The honest math: 3,330 MCQs at roughly 35 seconds per question (reading the question, thinking, answering, and skimming the explanation on wrong answers) works out to about 1,940 minutes — call it 32 hours. That's actual focused time. Most learners don't do it in a single block; spreading it over 4–6 weeks at around 60–90 minutes a day works well. Some topics are denser (seating arrangements, complex input-output) and will take longer; some go faster once you've internalised the pattern (series, basic coding).

If you're a few weeks out from a placement test, the realistic plan is foundations layer in week 1, depth layer in weeks 2–4, placement edge in weeks 5–6, with mixed-topic practice in the last week before the test.

The natural pairing is Quantitative Aptitude — the two together cover every aptitude section on every Indian campus-placement test. Take them in parallel rather than sequence; aptitude-test sections are mixed, and your brain switches between them anyway. After finishing both, run timed mock tests on Abekus to simulate exam pressure, then revisit topics where your accuracy drops below 70%.
